.VALVE- SPRING COMPRESSOR.

Patented Mai'. 15, 1921.

Application filed January 27, 1920. Serial No. 354,332.

To al?. whom t may concern.: Be it known that I, HARRY R. RANDLE- MAN, a citizen of the United States, residing Y at Long Beach, in the county of Los Angeles andrState of California, have invented' certain new and useful Improvements in Valve-Spring Compressors, of which the following is a specification.

The present invention relates to improvements in tools and, more particularly, to a tool adapted to be used for compressing valve springs and the like resilient bodies.

The primary object of the invention is to provide a 4tool of the above character' wherein the gripping jaws are maintained at a fixed angle with respectto each other and to the spring which is engaged, during the complete compressing operation thereby insuring efliciency in operation.

A further object of the invention is to provide a valve spring `compressing tool wherein the gripping jaws are so mounted with respect to the operating handles whereby the maximum leverage can be o-btained and which will permit ready removal of the jaws for the purposes of substitution or repair.

A still further object of the invention is.

to provide a tool of the character set forth above which is cheap to manufacture, strong and durable and which by reason of its lightness can be operated quickly and easily.

Various other objects and advantages of my invention will become apparent during the continuance of the following description.

In the drawings Figure 1 is a view in side elevation showing my invention iii its preferred embodiment; the gripping jaws being shown in an extended position.

Fig. 2 is a view similar to Fig. 1 showing the gripping jaws in aclosed or compressed position. Y'

Fig. 3 is a view in top plan of one of the Y gripping jaws.

In reducing my invention to practice I Y first provide complemental operating hanone end the handle portions 10 are offset as j at 13 in order to form a fulcrum for the gripping jaws which will be hereinafter described.

The gripping jaws 14; are pivotally mounted n ear their forward end upon the offset portion 13 of the handles 10, as at 15. At their rear end the gripping jaws .14 are slightly enlarged as at 16 which enlarged portion is provided with a slot 17 for the reception of the handle portions 10 as clearly shown in Fig. 1. From this it will be observed that while the pivot point of the gripping jaws is forward of the pivot point 11 of the handles, the jaws are prevented from being rocked on the pivot point 15 by reason of the handle portions passing through the slots 17 thereof. At their forward end the gripping jaws 14 are forked as at 18 to facilitate the engaging of the valve spring. The inner edge of the fork portion may be cut away and milled as at 19 in order to insure a better grip. v Then the parts are in the position shown 1n Fig. 1 the gripping jaws 14 as well as the hand gripping portions 12 of the handles 1Q are in an extended or open position. However, upon pressure being exerted upon the free end of the handle toward each other. the hand gripping portions 12 are, of course; moved in that direction and the gripping jaws will also be moved toward each other until the position shown in Fig. 2 is reached. During movement of the handles 10 the gripping jaws maintain the same angle with respect to each other and to the valve spring thus eliminating the possibility of the spring slipping from engagement with the aws or becoming broken because of the exertion of unequal pressure thereon.

What is claimed is 1. In a tool of the character described, a pair of crossed pivoted operating handles, a pair of jaws pivoted to said operating handles and means whereby said jaws are actuated substantially in parallelism, and forked spring engaging means on said jaws.

2. In a tool of the character described, a pair .of crossed pivoted operating handles, a pair of jaws pivoted to said handles forward of their pivots, said aws having a portion extending rearwardly from their pivots co-acting with said operating handles to actuate them substantially in parallelism,

and forked grip means on the forward ends Y of said jaws.

3. In a tool of the character described, a pairv of crossed pivoted operating handles, a pairrof jaws fulcrumed on said actuating handles forward of their pivot and having rearwardly yextending portions co-acting with said operating handles back of their pivot to maintain said jaws substantially parallel. during actuation, andV forked seats on the forward ends of said jaws.

4l. In a tool of the character described, a pair of crossed pivoted operating handles,

ljaws pivoted on said handles forward of their pivotal point and having rearwardlyT extending portions co-acting with said operf ating handles back of their pivotal point, the said rearwardly extending portions co-act-V ing withl the actuating arm on which the opposedjaw is pivoted, to maintain said jaws in substantially parallel actuating position andv forked seats on the forward ends of said jaws.

5. In a tool of the character described, a pair of crossed pivoted operating handles, jaws pivoted on said handles forward of their pivotal point and having rearwardly extending portions co-acting with said Voperating handles back of their pivotal point, the said rearwardly extending portions coacting with the actuating arm on which the opposed jaw is pivoted to maintain said jaws in substantially parallel actuating position,

said (zo-acting portions comprising slottedY members sli-dable 0n said handles, kand forked seats on the forward ends ofisaid jaws. Y

6. In a tool of the character described, a pair of pivoted operating handles having offsets at their forward ends, a pair of substantially parallel jaws'fulcrumed in said offsets on said vactuating handles forward of their pivot and having rearwardly extend-V ing portions eo-acting with said operating HARRY R. RANDLEMAN.
